有個自訂類別
public class Node {
public Node(String name,String type){
this.name = name;
this.type = type;}
public int hashCode() {
int result;
result = this.name.hashCode();
return result;}
public boolean equals(Object other){
if(((Node)other).name.equals(this.name))
return true;
return false;}
}
public static void main(String[] args)
{
Node n = new Node("Lin","Human");
Node k = new Node("Lin","alien");
public static Set<Node> set = new LinkedHashSet<Node>();
set.add(n);
set.add(k); //會視為相同物件，不加入set
想請問有辦法在判斷是相同物件時執行我想自訂的方法嗎?
比如說：當set.add(k)時發現set裡面有相同物件時執行System.out.print("已有相同物");
}
